Why is carbon uniquely suited to form biological molecules?

• Carbon can form up to 2 bonds with other atoms.

• Carbon has 4 valence electrons, allowing it to form up to 4 bonds with other atoms.

• Carbon is a metal and can conduct electricity.

• Carbon is a noble gas and does not react with other elements.

What types of bonds can carbon form with other elements?

• Only single bonds

• Single and double bonds

• Single, double, or triple bonds

• Only triple bonds

What allows for a huge variety of molecules with varying properties and functions?

• Carbon's inability to form bonds

• Carbon's ability to form complex large molecules

• Carbon's limited bonding capacity

• Carbon's inability to form cyclic shapes
